Collector Data

Download Quarterly CN Data

bash

cd qlib/scripts/data_collector/pit/
# download from baostock.com
python collector.py download_data --source_dir ~/.qlib/stock_data/source/pit --start 2000-01-01 --end 2020-01-01 --interval quarterly

Downloading all data from the stock is very time-consuming. If you just want to run a quick test on a few stocks, you can run the command below

bash

python collector.py download_data --source_dir ~/.qlib/stock_data/source/pit --start 2000-01-01 --end 2020-01-01 --interval quarterly --symbol_regex "^(600519|000725).*"

Normalize Data

bash

python collector.py normalize_data --interval quarterly --source_dir ~/.qlib/stock_data/source/pit --normalize_dir ~/.qlib/stock_data/source/pit_normalized

Dump Data into PIT Format

bash

cd qlib/scripts
python dump_pit.py dump --data_path ~/.qlib/stock_data/source/pit_normalized --qlib_dir ~/.qlib/qlib_data/cn_data --interval quarterly
